She could be heard squealing as Robbie showed off his pants to the audience

As his wife Ayda Field looked on in mock astonishment, Robbie turned to her and said: “That wasn’t the face you were pulling last night.”

Proudly showing his pants off to the audience, Robbie explained he’d become a big fan of wearing the pants as often as he could – before hurriedly explaining he had more than one pair.

The Let Me Entertain You Star is a guest on the show alongside his wife of six years.

Coleen previously struggled to contain her excitement as her fellow panellist Ayda revealed her husband was appearing on the show, telling the audience: “I’m so excited about that…but sadly you’re coming with him though – I can’t even flirt with him!”

Coleen however did try her best to flirt with Robbie, joking she’d join him in the bath to listen to his songs, just like he does with her wife.

She was rewarded for her efforts later in the show when she got to kiss Robbie – not once, but twice.

Looking at Ayda, Robbie said: “How many husbands get told to do it again when they’re kissing another woman?”
